twice about hosting a mailing list. I'm not sure what the answer is
here; perhaps mailing lists need to (somehow) take weaker responsibility
for messages that pass through them.
I am at a loss to understand why people keep proposing schemes that have
no utility other than to help give a free pass to various kinds of spam.
Who is proposing a scheme here? I said I'm not sure what the answer is.
If you're saying that replay isn't something that signatures should
attempt to address, I entirely agree.
R's,
